Lunyu II. 22. (38)

The necessity to a man of being truthful and sincere.
The Master said, "I do not know how a man without truthfulness is to get on. How can a large carriage be made to go without the crossbar for yoking the oxen to, or a small carriage without the arrangement for yoking the horses?"

Legge II.22.

The Master said, 'I do not see how a man can be acceptable who is untrustworthy in word? When a pin is missing in the yoke-bar of a large cart or in the collar-bar of a small cart, how can the cart be expected to go?'
